Dear FOMers,
I think that realism and a commitment to intuitionistic logic are
compatible (I can imagine such a view, though I do not hold it).
So I agree that "bivalence" can be viewed as a separate issue from
ontology.
But I find the attempt to construe Godel as a "weak realist" of this
kind quite incredible. It is very clear from his essay on the continuum
problem (and even from the excerpts exhibited on the list) that he was
a realist in the strong sense that mathematical propositions, whether
we know how to decide them or not, are either true or false.
